In this work an attempt has been made to compare the effect of rotating copper electrode for machining of HCHCr D2 steel at different sets of rotation i.e. 60,100 and 200 rpm. e intent of the present study is to observe the effects of input parameters such as peak current, on time, duty cycle, rotational speed of electrode on the material removal rate (MRR) and surface roughness (SR). It is observed that material removal rate of Cu electrode at lower RPM is higher at lower value of duty cycle and depends directly on values of current. e electrode wear rate is lower at higher RPM and increase with increase in current. Surface roughness holds a higher value at increased rotational speed and at greater values of duty cycle but lower at reduced duty cycle. e result shows that at higher speed of rotating electrode the MRR decrease whereas the surface roughness increases, at different levels of peak current and duty cycle. Percentage contribution of parameters like current, duty cycle and on time is calculated, on each set of RPM, through ANOVA and it's found that current has the greatest effect on MRR followed by duty cycle and on time.
